"Haha, we are here to ask you for your business, of course we don't dare to bother you too much. Of course, it will be beneficial to you. You may be able to have more high-tech in the future." Director Yang didn't say much, and went straight to the topic. According to He Ku's explanation, the lamp beads that need to be made are also cross-ages, brighter than the current headlights, but more power-saving.

Director Yang's words were very serious. Director Peony did not dare to be careless and took everyone to the newly opened R&D workshop.

The Peony Factory Manager proudly introduced: "This is the talent team of our factory. The laboratory has a complete range of materials. You can directly say if you have any needs."

Director Yang nodded and signaled why he started.

After thinking about it, why kuk took out a piece of domestic lamp bead craftsmanship information and handed it to everyone to read. This is a product that imitated someone else's in the 21st century. It can be produced in small workshops in the future, which is not difficult for radio plants.

Of course, there are also some cost issues to consider, because the process of genuine products is too complex, the cost is five times that of imitation products, but the performance is only 1.2 times that of imitation products. The authentic products are not cost-effective.

After taking a look at the complete equipment here, He Ku was a little itchy and planned to make his first lamp bead by himself. "I found that the tungsten filament light bulb was not bright, which greatly affected our nighttime operation. After thinking about it, I imagined a light emitting diode, temporarily called LED, and whatever it calls it in the future, as everyone likes. Since it was just an idea, I planned to test it on the spot, and now I need some materials to make a new compound."

Director Yang looked at Director Mudan proudly, "Look, let Xiao Ku demonstrate to you first, and then just take a picture of the cat and the tiger. As far as I know, there is nothing he can't do."

"Look, learn quickly, we must grasp these things firmly." Director Mudan solemnly instructed the scientific researchers around him.

Take out two materials from the bottles and jars in the laboratory. He Ku put on a gas mask and protective gloves and said lightly: "In this way, everyone should take good protection first. I will make a simple compound first. Since it is a compound of nitrogen and gallium, we will temporarily call it gallium nitride. According to my research, we can temporarily get it. I will call it the film method and the sol-gel method."

After experimenting with both methods, He Ku started the next step, "Very good, this is gallium nitride. This compound has a structure similar to wurtzite and has a very high hardness. We use these gallium nitride as a basis to make some epitaxial tablets..."

"Everyone needs to check the mask again. I need some fluorescent powder applied to the imaging tube, which is highly toxic..."

"I plan to make these diodes into one hundred small lights, and the next thing is the key point..."

.....

"The epoxy resin is sealed to protect the function of the inner core wire..."

After more than an hour, I walked the entire production process in the laboratory and then welded the lamp beads to the circuit board equipped with the voltage regulator. "One lamp bead has a power consumption of 40,000 yuan, and five small diodes. Let's try welding ten lamp beads first!"

At this moment, many people were puzzled. Why is the difference between the incandescent lamp and it looks like a small square piece, or how to light it with half a fingernail? Can this thing be bright?

After powering on, He Ku looked at the results and found that one was not lit. "Oh, one failed, it was a waste. Hey, it didn't fail, it was a false welding."

At this moment, everyone's attention was all on the lamp. At this moment, the light emitted by the ten lamp beads directly pressed over the sunlight in the house. You can see the lamp beads glowing at a glance, and it is very dazzling.

What He Ku said was very simple. After listening to it, the researchers understood it. At this moment, many R&D personnel rubbed their hands excitedly and couldn't help but try it out by themselves.

The director of Peony even took a breath of air conditioning, "Hiss! A 4W lamp actually looks brighter than a 40W tungsten wire bulb! Ten pieces are connected in series and they are simply a big power searchlight!"

Director Yang looked at the lamp beads excitedly and patted He Ku's shoulder, "The lamp beads are made into flashlights, and each of our factory's outstanding employees will be taken away later."

He Ku responded and drew a simple drawing on the spot, "Okay, factory manager, I will draw a simple circuit diagram to make a circuit board later. Our factory will polish some of the shells by ourselves, so we can make them custom."

Director Yang looked at him with satisfaction and patted the already dumbfounded Director Peony, "It's up to your factory to make the circuit board, we still can't do it."

Leave some information, and looked at the many clerks and solemnly instructed: "I can only do this, and leave the rest to you. The current products are just rough test items. If possible, at least twenty LED diodes are needed for the lamp beads with a fingernail! How should the specific mass production be produced, or whether it is worth mass production, is all up to you."

Although everyone is satisfied with half the size of the fingernail, He Ku is still disappointed with this. The strong light flashlights in later generations can be equipped with seventy or eighty LED diodes in such a large place, and some can even hundreds of them.

Such lamp beads, combined with a metal shell, can adjust the light emitted through the lens. If the long shot is tens of meters away, it will be easy. If the troops are equipped and the situation at night is illuminated by the opponent, it can temporarily blind people, and this moment will be fatal.

After answering some questions, why don’t you plan to try making a laser sight?

"Comrade Xiao Ku, we are studying color imaging tube technology. Can you give us some advice?" asked Peony Factory for a long time.

"I don't understand!" He Ku shook his head.

"You can say a few words, even if it's nonsense, we want to change our thinking." Many scientific researchers looked at Heku eagerly.

Director Yang looked at Director Peony proudly and patted He Ku's shoulder, "Say a few words, go to their first-grade tofu at dinner time!"

"Yes, yes, yes, eat any first-grade tofu!" Director Peony immediately made a statement.

I really don’t understand the color TV of the display tube. This thing is too complicated and I really can’t get out of it for half a lifetime, but I can still copy homework. I will tell you how to do it and what to do, and the difficulty will be greatly reduced.

"Okay, I'll just talk nonsense." The factory manager said, and he couldn't help but give face.

After clarifying the idea, He Ku said lightly: "As far as I know, the three basic colors of red, green and blue can theoretically form any color, and ours can start in this aspect."

On the other hand, He Ku prepared a complete set of information. This time he took out the most original imaging tube, three guns and three beams of color imaging tubes, but even so, it is complex enough. It consists of four parts: fluorescent screen, shade mask, electronic gun and glass shell. There are three independent electronic guns, arranged in the shape of a product, and emits three electron beams, red, green and blue respectively.
